IN V EN TORI Herberf GOTTSCHING mm d? m AffOInQI PATTERN INSTALLATION F OR CIRCULAR KNITTING MACHINES BACKGROUND OF THE INVENTION The invention concerns a pattern installation for circular knitting machines with a rotating needle carrier, where a selection of needles is being carried out by means of setting elements which are being actuated electromagnetically according to the pattern. Pattern attachments, where setting elements are actuated electromagnetically in order to select needles have already been proposed several times (Swiss Pat. No. PS362,787 and German Pat. Nos. 438 387, 669 565, 630 794, 581 892). With all these known pattern installations, however, the problems which are encountered, especially the rapid and safe working of the electromagnets, the flawless holding of the setting members which act upon needles or pattern jacks, and a low amount of effort and safety in operation, have so far not been solved in a satisfactory manner.
SUMMARY OF THE INVENTION It is an object of the invention to produce a pattern installation for circular knitting machines, which works through elements which act electromagnetically where a safe displacement of the needles and pattern jacks can be obtained, and which can be controlled easily by electronic means according to the requirements of the design.
According to the invention, this object has been achieved by causing the setting elements which act upon the control jacks of the needles, which are supported in the needle beds in a displaceable manner, to be connected either directly or indirectly with the armature of polarized control magnets which are arranged at the needle selection point of the pattern installation so that several of them are set out in a staggered formation, and which has at least one, preferably impulse supplied, control winding with the aid of which, it is possible to adjust the armature between two stable positions.
The polarized control magnets each have two separate permanent magnet circuits with opposing directions of flow and adjustable air gaps and an electromagnetic circuit which is superimposed upon both permanent magnet circuits and which acts upon a common armature. In order to ensure a safe control, the installation according to the invention holds the entire air space width between the armature and the core of the electromagnet constant in each position of the electromagnet. This result can be obtained by constructing the common armature of the control magnets in the form of a rod and by providing it in the magnetic throughflow areas with two conical sections, which are distant from each other and opposite to each other. These act with identical conical cutouts of an electromagnetic core which has small plates, in such a way, that when there is an axial displacement of the armature, the air space between one of the armature cones and the electromagnetic core becomes smaller and the air space between the other armature cone and the electromagnetic core becomes larger.
An important advantage of the pattern installation according to the invention can be based upon the fact that it is possible because of the features of the invention to construct the control magnets as flat bodies where the partly multi-part laminated magnet cores and the like are connected with each other by means of frame and bow members and are held in their opposing positions.
The demands for the lowest possible energy requirement for working the pattern installation has been met according to the invention, on the one hand, by springs supporting the armature of the control magnet in a friction free manner and, on the other hand, by also springs supporting the setting members which are indirectly connected with the armatures of the polarized control magnets including the interposed setting and intermediate elements. The result is that the pattern installation works with little loss of energy. An undesirable return adjustment of the setting elements through counter forces of the butts of the jacks or needles on the setting member is prevented by locking elements which work together with the setting members. The locking elements, according to the invention, are connected together to a common adjustment element.
BRIEF DESCRIPTION OF DRAWING Further features of the invention can be obtained from the following descriptions in combination with the drawing, where a constructional example of a pattern installation built according to the invention is schematically shown in several views in which:
FIG. 1 is a central longitudinal section through a polarized control magnet of the pattern installation which is formed as a flat body;
FIG. 2 is a portrayal of the control magnet corresponding to FIG. 1 in which only the conductor bodies for the lines in the magnetic field are shown and where the magnetic flow circuits have been entered;
FIG. 3 is a portrayal of several of the control magnets which have been allotted to a patterning installation in their opposite positions with various sectional portrayals of the control magnets according to the section lines 1-1 to 77 which have been entered in FIG. 1;
FIG. 4 is a section along line IV-IV in FIG. 3 through a pattern installation with a portrayal of the adjustment mechanism between the control magnets and the jacks; and,
FIG. 5 is a portrayal of a pattern installation which has been mounted on a circular knitting machine.
DESCRIPTION OF PREFERRED EMBODIMENTS FIGS. 1 to 3 show the construction of control magnets 10 which have been formed as flat bodies. They each have two frame parts 11 and 12 separated from each other which extend along their longitudinal sides and which are connected with each other by means of transverse bridges, not shown.
Situated in the frame parts in the central area are two electromagnetic cores 13 and 14 which are formed from plates arranged in layers, two pairs of permanent magnets 15, 16 and 17 and 18 and soft iron bridges 19 and 20. The two soft iron bridges l9 and 20 are adjustably arranged in the frame parts 11 and 12 for adjustment in the direction of the longitudinal axis of the control magnets in a manner not further described, so that the width of the air space which they form together with the permanent pair of magnets 15, 16 or 17, 18 respectively, which are allotted to them, can be altered. In the construction example which is portrayed here, the air space between the soft iron bridge 19 and the two permanent magnets 15 and 16 have been fixed by means of small inserted spacer plates 21 which are made from a non-magnetized material. In the same way, small spacer plates 22 have been inserted between the soft iron bridge 20 and the permanent magnets 17 and 18. Electric coils 23 and 24 are wound around the two electromagnet cores l3 and 14.
The control magnet has an armature 25 which is in the form of a rod with its two ends 251 and 252 on either side protruding beyond the magnets. The rod is equipped with two spaced cones 26 and 27 which are directed opposite to each other. These two cones 26 and 27 coact with corresponding conical limitation surfaces 131 and 141 or 132 and 142 in such a way, that with an axial displacement of the armature rod 25, the air gap between cone 26 and surfaces 131, 141 diminishes while the air gap between the other cone 27 and the conical limitation surfaces 132 and 142 of the two electromagnetic cores 13 and 14 is enlarged to the same extent, so that the total air gap which exists between the two cones 26 and 27 and the two electromagnetic cores l3 and 14 has the same dimension in each position of the armature rod 25. The limitation surfaces 131, 132 and 141, 142 of the electromagnetic cores have been given a surface cover which cannot be magnetized, so that they make the release of the cones 26 and 27 easier when reversing the polarized control magnets.
